Answer:
Step-by-step explanation:
BDC=95
769.3= (3.14) r^2 *5
153.86=(3.14) r^2
49= r^2
The square root of 49 is 7
The answer is 7.
Answer:
Step-by-step explanation:
y = 9x + 8
y = 7.5x + 16
1.5x = 8
x = 5.3 hours
Answer:
9.2
Step-by-step explanation:
we can use the pythagorean theorem to find the hypotenuse between the centre of the circle and the midpoint of the line segment.
hence,
x = sqrt(36 + 49)
x = 9.21
Well you need to explain what is going on here so try to rephrase this.
